Vintage Folding Aviator Sunglasses Blue Gradient Lenses w/ Carrera Case

Vintage folding aviator-style sunglasses featuring dark blue gradient lenses and a black metal frame.  Unique compact folding design allows the temples and lenses to fold inward for storage. Includes the vintage Carrera-branded zippered case shown in the photos, which is sized for compact/folding eyewear.  IMPORTANT: The sunglasses themselves do not have any visible Carrera branding, model number, or other identifying marks that I can find. Because of this, I cannot verify that the sunglasses were manufactured by Carrera. They are being sold as unbranded vintage sunglasses with a Carrera case included.
